# GDM Configuration Customization file.
#
# This file is the appropriate place for specifying your customizations to the
# GDM configuration. If you run gdmsetup, it will automatically edit this
# file for you and will cause the daemon and any running GDM GUI programs to
# automatically update with the new configuration. Not all configuration
# options are supported by gdmsetup, so to modify some values it may be
# necessary to modify this file directly by hand.
#
# To hand-edit this file, simply add or modify the key=value combination in
# the appropriate section in the template below. Refer to the comments in the
# gdm.conf file for information about each option. Also refer to the reference
# documentation.
#
# If you hand edit a GDM configuration file, you should run the following
# command to get the GDM daemon to notice the change. Any running GDM GUI
# programs will also be notified to update with the new configuration.
#
# gdmflexiserver --command="UPDATE_CONFIG <configuration key>"
#
# For example, the "Enable" key in the "[debug]" section would be specified by
# "debug/Enable".
#
# You can also run gdm-restart or gdm-safe-restart to cause GDM to restart and
# re-read the new configuration settings. You can also restart GDM by sending
# a HUP or USR1 signal to the daemon. HUP behaves like gdm-restart and causes
# any user session started by GDM to exit immediately while USR1 behaves like
# gdm-safe-restart and will wait until all users log out before restarting GDM.
#
# For full reference documentation see the gnome help browser under
# GNOME|System category. You can also find the docs in HTML form on
# http://www.gnome.org/projects/gdm/

Activate side-mouse-buttons in FireFox

Just add two lines to xorg.conf will activate side-mouse-buttons in FireFox. This should work with most 5-button mouse. Here is a list of mice that worked with this instruction.

Logitech MX510

Logitech MX518

Logitech MX700

Intellimouse Explorer (first edition)

Backup Gnome configuration file

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak

Modify the Gnome configuration file

gksudo gedit /etc/X11/xorg.conf

Find the Input Device section for your mouse and add two lines as shown below. You may also increase the number of buttons if your mouse has more than 7, just fix the rest of the section based upon the number of buttons (remember back/forward, wheel click & tilt left/right all count as buttons)

At this point you can reboot your computer or reboot Gnome (Ctrl-Alt-BackSpace) to see if your forward/back buttons work in FireFox. They still won't work in Nautilus yet until you install the imwheel dameon.

How to detect CPU temperature, fan speeds and voltages (lm-sensors)

#!/bin/bash
# Here you can set several defaults.
# The number of devices to create (max: 256)
NUMBER=32
# The owner and group of the devices
OUSER=root
OGROUP=root
# The mode of the devices
MODE=600
# This script doesn't need to be run if devfs is used
if [ -r /proc/mounts ] ; then
if grep -q "/dev devfs" /proc/mounts ; then
echo "You do not need to run this script as your system uses devfs."
exit;
fi
fi
i=0;
while [ $i -lt $NUMBER ] ; do
echo /dev/i2c-$i
mknod -m $MODE /dev/i2c-$i c 89 $i || exit
chown "$OUSER:$OGROUP" /dev/i2c-$i || exit
i=$[$i + 1]
done
#end of file

Make this file executable, then run it

sudo chmod +x mkdev.sh
./mkdev.sh

Now detect sensors, and answer "y" to all questions.

sudo sensors-detect

Load the modules into kernel

sensors -s

Now, let's see the output

How to control fan speed (lm-sensors)

Install and config lm-sensors first, see section above. Then run pwmconfig to test your fans

pwmconfig

If you can control fan speeds, great. Now creat a file called /etc/init.d/fancontrol, and paste in the following

You need lm-sensors to display CPU temps, fan speed, and voltages in GKrellM.

You need nvidia driver to display nvidia GPU temperatures.

You need hddtemp to display harddrive temperatures

GKrellM is a hardware monitor that can display CPU and GPU temperatures, fan speeds, voltages, CPU load, network load, disk activity, disk temperature, memory usage, and swap usage. The installation is very easy, and configuration is just a few mouse-clicks. You can set alerts to warn you if the CPU is too hot or there is a fan failure. The hddtemp utility works with GKrellM to allow it to sense the disk temperature, as keeping your disks cool (e.g. less than around 40C) will allow them to last longer than if they run continually at higher temperatures (e.g. above 50C).

sudo apt-get install gkrellm hddtemp

To run the program

Click Applications -> System Tools -> GKrellM

To configure the settings,

Right click on GKrellM -> Configuration

I was struggling with lm_sensors before, but it doesn't detect all of the sensors on my computer. Later I found "GKrellM". It displays the GPU temperature on my nVidia 6600 GT out of the box. GKrellM also has plugins that show weather info, set reminders, etc.

Add an audio alert (optional Step):
Here is how to play an audio message when the CPU is too hot or a fan fails. First you need to find or record your own audio alert files. (I use Audacity to record my own.) Then go to:

Paste ONE of the following lines into a Terminal window first to test the sound. If you have two sound cards, you can use "-ao oss:/dev/dsp1" option to route the sound to the second sound card. Modify the file path and name so it points to the correct file. If you can hear the sound, then copy that line to a command line text field on the GKrellM's Alerts window.

How to install a Wacom tablet

For a detailed guide with screenshots about how to configure the "Extended input devices" in your graphic applications, please follow the official Dapper guide at https://wiki.ubuntu.com//Wacom

With the version of the Linux Wacom driver (0.7.2) in Ubuntu 6.06 Dapper Drake, if you unplug you tablet, it won't function when you plug it back in and you will have to restart X. For this reason, it is best to leave the tablet plugged in. This limitation will be removed when the 0.7.4 version of the driver is included in Ubuntu.

1. Using Synaptic package manager1, check if the packages xserver-xorg-input-wacom and wacom-tools are already installed - if not, install them. If you prefer using the command line, you can also execute :

sudo apt-get install xserver-xorg-input-wacom wacom-tools

2. Save a copy of your /etc/X11/xorg.conf :

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

then edit it with the command line :

gksudo gedit /etc/X11/xorg.conf

and change all /dev/wacom occurences into /dev/input/wacom (created by wacom-tools udev scripts), then save the file.

You should be ready to go after you have restarted X. Remember to configure the "Extended input devices" in your graphic applications (Gimp, Inkscape), however you can already check if it's working by moving your stylus on the tablet : the mouse cursor should go through the whole screen.

How to enable Multicore Support

This should work for both Multicore systems and SMP systems

sudo apt-get install linux-686-smp

You can check that this works by running the following and seeing two CPUs listed

The above lines change the default file in three ways: the application is placed in the Application/Internet category, gksudo will make the application run as superuser and we put a nice icon that appears in the menu.

Start the client with Applications -> Internet -> PPTP Client

How to Configure Ubuntu/Kubuntu with WPA using Network-Manager

Ubuntu Dapper in typical cases can configure WPA to work out of the box with minimal hassle. You'll need to install network-manager.

For Ubuntu:

sudo apt-get install network-manager-gnome

For Kubuntu (will install knetworkmanager):

sudo apt-get install network-manager-kde

Logout/Reboot.

Ubuntu users should now see the NetworkManager Applet in the Gnome notification area. Kubuntu users will probably have to run knetworkmanager before they see NetworkManager in the systray.

If instead, you get a "The NetworkManager applet could not find some required resources. It cannot continue." message, then:

sudo gtk-update-icon-cache -f /usr/share/icons/hicolor

Once Network-Manager is installed, click on the NM icon in the notification area (default is at the top right of Ubuntu/Gnome). Choose your network, then enter your passphrase. Type a password for the keyring, and you're set.

Note: If you installed Kubuntu then installed ubuntu-desktop & network-manager-gnome, you may not be able to use network-manager in Gnome, if at all. In this case, you may have to use WPA Supplicant and do some manual editing of conf files to get WPA up and running.

Note: When you first log into Gnome/KDE, the keyring application will ask for a password. Future revisions of Network-Manager should resolve this.

If you reboot now, the disk will be writable to the selected users when they logon. If you want the changes to take effect immediately without rebooting, execute the following command, ignoring the errors about "/" and others not being unmounted. You'll have to logout from all your user sessions for the new group to be acknowledged (usually a logout from your graphical session and login back again will do it).

This will make it so your grub console will require a password to edit the lines, and the recovery modes won't work unless the password is typed. To access the other grub options at the menu, follow the instructions at the bottom of the screen. It will be something like pressing p and typing your password.

How to disable history listing in Console mode

export HISTFILESIZE=4
unset HISTFILE=5
# Change this to a reasonable number of lines to save, I like to save only 100.
export HISTSIZE=1
# Ignores duplicate lines next to each other
export HISTCONTROL=ignoredups

This will disable Bash history for the user, retaining keystroke history and recall to use while limiting recall history to 100 lines. This will also not record duplicate lines next to each other.

What: Quote from Wikipedia: "LoJack is an aftermarket vehicle tracking system that allows cars to be tracked by police after being stolen. The manufacturer claims a 90% recovery rate. The name "LoJack" is a play on the word "hijack," meaning the theft of a vehicle through force."

Why: If your laptop is ever stolen and connected to the Internet. You will be able to find out from what IP it connects to the Internet from and contact the authorities.

How:

Get a free dynamic IP account from one of the many providers. Here we will use DynDNS.

How to boot into Windows installed on a seperate SATA drive

This configuration applies to people who have Linux installed on a IDE drive, and Windows installed on a seperate SATA. The IDE drive boots first, so we need to add an entry to the boot menu on the Linux disk. Here we assume the name of your Windows drive is hd1. If you are not sure, click the link above to find out.

How to apt-get the easy way (Synaptic)

In the Installation Media tab, click Add. There are three separate repositories; Dapper Drake, Security Updates and Updates. Select each repository and check Officially supported, Restricted copyright, Community maintained (Universe) and Non-free (Multiverse). Ensure you click OK between each repository to save your changes

You should now see those three repositories under Channels. Make sure Officially supported, Restricted copyright, Community maintained (Universe) and Non-free (Multiverse) appears under each repository

To add backports and PLF (new versions of many applications. Unsupported. May contain illegal packages. Use at own risk.)

Settings -> Repositories

Click on Add and then Custom

Paste the following four lines into the box and click Add Repository, one line at a time:

How to compile .deb files from source

There are various programs available to help automate the process of create .deb files from source. For more information, see the links at the end of this section. A basic well tested method is described here.

Install the necessary software to build the source (build-essential may be all that is necessary, though there may be other dependencies) and checkinstall (which creates deb files).

sudo apt-get install checkinstall build-essential

In the directory where you have extracted the source, after you have run ./configure and make you can create a .deb file and install it with either of the following commands. The second -D option creates a .deb file in the directory that you can share with others or install without needing the source.
